Tri-Sprintec - I lost a pill (day 2). It fell and I can't find it anywhere. What should I do?

If you miss a pill whether it is here or at the end of your cycle, you are going to have to use condoms for a week after the missed pill or you could get pregnant. Keep looking, if you dropped it on the floor, it is there somewhere, get a bright flashlight out and keep looking. If you cant find it you can skip the pill now and use condoms as back up for seven days or you can do it at the end of the cycle. If you do it at the end of the cycle you wont be protected during your "period" days as you normally would be so again using condoms as back up x 7 days.
